During a Breaking Bad marathon last night, AMC slipped in a few seconds of the show's upcoming spin-off Better Call Saul, which is set to bow in February. It features Saul Goodman (Bob Odenkirk) making a lame joke comparing lawyers to health insurance. (I think the joke is that Saul makes bad jokes.)

While they're still working through plot, they anticipate the series being set in an office with a much lighter tone than that of its predecessor. If Bad was 75 percent dramatic and 25 percent comedic, Saul will be the opposite. The challenge has been finding the dramatic tension in their lead character. Unlike Walter White, who was damaged and needy, Saul has been portrayed as happy-go-lucky until now. Says Gilligan, "We've had to find the ongoing itch that Saul needs to scratch, so to speak, or else we wouldn't have much of a show."

...Both [Bryan Cranston] and Aaron Paul, in addition to some of Bad's other actors, have expressed interest in making appearances, which Gilligan intends to make happen. "Personally, I'd have a hard time resisting putting all these guys in for a cameo or two every now and then," he says, smiling at the very thought...Gilligan says he envisions being in the writers room full-time, at least for the first season, and already is slated to direct the pilot. Once Saul has found its footing, he'll turn his focus to other projects — assuming he is able to detach.

The official synopsis of Better Caul Saul on AMC's site reads:

Better Call Saul is the prequel to the award-winning series Breaking Bad, set six years before Saul Goodman (Bob Odenkirk) became Walter White's lawyer. When we meet him, the man who will become Saul Goodman is known as Jimmy McGill, a small-time lawyer searching for his destiny, and, more immediately, hustling to make ends meet. Working alongside, and often against, Jimmy is "fixer" Mike Erhmantraut (Jonathan Banks), a beloved character introduced in Breaking Bad. The series will track Jimmy's transformation into Saul Goodman, the man who puts "criminal" in "criminal lawyer."
